need to know your draw legnth. a bow with 60-70lb limbs can be set from atleast 60-70lbs.
if you arent comfortable drawing 70lbs and you buy arrows spined for 70lbs you will run into spine issues...
find out your draw legnth and arrow legnth and report back for better help...or let the shop do it for you..
good luck....not trying to confuse you...i just dont know any way to shop for arrows and correct spine without arrow legnth and draw weight
we can all guess...but thats not something i like to guess at. poorly spined arrows will cause headaches....i learned my lesson once
